UtilityHandle - Utility handle

Utility handle are used to manage complex applications, which have at least two data sources. Usually, a utility handle allows defining a system data source ([SYSTEM] section), and a data source for source and target or resource and data data base. The intention of the UtilityHandle class is supporting many typical applications based on such three data sources.

An application allows not more than one utility handle. The UtilityHandle is available after constructing the UtilityHandle by calling the static UtilityControlBlock () function.

Instead of using the UtilityHandle class, one may also manage a number of data sources ( DataSourceHandle ) in the application. More simple applications referring to only one data source should use the DataSourceHandle class anyway.
